VEHICLE-SPRING.

SPECIFICATION forming part of Letters Patent No. 377,584, dated February7, 1888.

v Application filed May 17, 1886. Serial No. 202,371. (No model.)

To aZZ 'whom it may concern.-

Be it known that I, EDWARD STORM, of Poughkeepsie, in the county ofDutchess and State of New York, have invented a certain new and usefulImprovement in Vehicle- Springs, of which the following is aspecification.

My improvement relates to the class of vehicle-springs which, operateupon the torsion principle.

I will describe my improvement in detaiLand' then point out the novelfeatures in the claim.

In the accompanying drawings, Figure 1 is a plan or bottom view. Fig. 2is a perspective plan or top view of the same. Fig. 3 is a portion of aplan or bottom View showing a modified form of construction. Fig. 4c isa portion of another plan or bottom view showing another modification.

' Similar letters of reference designate corresponding parts in all thefigures.

A B designate a frame, of which A designates the side pieces, and B theend pieces or sills. This frame may be secured together in any suitablemanner.

O designates side bars, and D end bars or bolsters, such as areordinarily employed in what is termed a side-bar vehicle.

E designates spring-bars,which may advantageously be made of steel, andwhich will preferably be angular in cross-section. These bars, as shown,extend from front to rear of the frame A B, and are rigidly secured neartheir ends to the sills B by clips or keepers a.

F designates arms or levers, of which I have shown four. These armsextend at approximate right angles to the bars E. Near their inner endsthey are rigidlysecured to the bars E, and at their outer ends they aresecured to the side bars, 0, by means of clips or couplings b, which maybe of the usual or anydesired construction. These arms or levers may bebentlongitudinally into any desired shape. It will be observed that thedistance between the arms F, secured to each of the bars E, is greaterthan the distance between said arms and the sills.

In case it is desired to shorten the springbars E, I may placeadditional sills,-J, adjacent may be secured. By this means the lengthof the springs may be regulated as desired.v I have shown such anarrangement in Fig. 3.

In Fig. 4 I have shown the end of one ofv the spring-bars E as bent insuch manner as to to lie against the sill. V Y By my improvement I doaway with the use of a sill between the end' sills, B, such as iscommonly employed, whereby I obtain not only the advantage of thetwisting or torsion of the spring-bars E, butalso a longitudinalflexnre. I also do away with journals atthe ends of thespring-bars,which is a common method of construction.

By my improvement the ease of the springs is increased, while their costof manufacture is lessened. I

I am aware that a torsion-spring has been made comprising a spring-barconstructed of a single piece of metal and bent in such' manner as toform an approximately rectangular frame. Said frame is secured to thewagonbody by means of clips, and levenarms extendfrom the side bars andare connected to the side portions of the spring. By my improvement I amenabled to remove or replace either one of the spring-bars withoutdisturbing the other, in case it should become necessary from breakageor other cause. In the construction referred to it would be necessary toremove the entire spring-frame.

What I claim as myinvention, and desire tosecure by Letters Patent, is-

The combination, with a wagonbody, of sills adjacent to the ends of saidwagon-body, side bars, torsionsprings extending between said sills ofapproximately the same length as the wagon-body, anda pair of armsextending from each of the side bars to each of said springs and rigidlysecured to the springs near their ends, 'sothat there will be a greaterdistance between the arms for each spring than between said arms and thesills, substantially as specified. v
